I'd really like you to help me. I'm trying to install the library on windows vista IGRAPH following recommendations from the website and using cygwin. I downloaded the library, I descompress the file; then downloaded cygwin and finished after installation typed the 4 commands (./configure; make ; make check and make install). When I try to compile a program written in C code the following error is issued : <No such file or directory>; ie from what I understand it is not recognizing the library (igraph.h). Please guide me as to what I should do to solve the problem.
Thank you.
